Semen analysis/DFI

Semen analysis and DNA Fragmentation Index (DFI) are crucial components of male fertility testing. They provide valuable insights into a man’s reproductive health and can help identify potential causes of infertility. Here’s some content explaining these concepts:

Semen Analysis: Understanding Male Fertility

Semen analysis is a fundamental test used to evaluate male fertility. It involves examining a semen sample to assess various parameters that can impact a man’s ability to father a child. The key aspects evaluated in a semen analysis include:

WHO CRITERIA OF SEMEN ANALYSIS

  • Sperm concentration – As per the World Health Organisation (WHO), your sperm count should be at least 15 million sperm per millilitre of semen.
  • Sperm motility – Your sperm motility (activity) should be 50%, meaning that at least half of your sperm cells should be active.
  • Sperm morphology – The shape and size of the sperm (morphology) are also analysed. Research suggests that at least 4% of your sperm cells should be normally shaped.
  • Semen volume – Your fertility doctor will also test if you are able to produce enough semen. Ideally, you should be able to ejaculate at least 1.5 millimetres of semen.
  • pH level – Your semen should not be too acidic. The pH level of your semen sample should be between 7.1 to 8.0.
  • Liquefaction – Normally, semen comes out as a thick ejaculate and later becomes liquid. The time taken for the semen to become thin in a liquid form is called liquefaction time. Liquefaction time is ideally 20 minutes.
  • Semen fructose – Semen analysis also measures semen fructose levels which are contributed by seminal vesicles. If no sperm is found in the semen, fructose levels are checked to identify obstructions.
  • Appearance – Semen fluid is usually greyish and opalescent. If your semen sample has a red tint, it indicates the presence of blood while a yellow-tinted sample may indicate jaundice.

 

What does an abnormal semen analysis report indicate? 

An abnormal semen analysis report indicates a poor chance of getting the female partner pregnant. However, it should be noted that a semen analysis is not the only factor in evaluating male factor infertility.

Abnormal semen analysis reports may indicate infertility, infection, hormonal imbalance, underlying diseases (diabetes), and genetic defects.

Semen analysis results also vary on the individual’s age and overall health.

Your fertility doctor will indicate additional testing and screening to confirm or rule out other conditions including:

  • Blockages preventing the release of sperm into semen
  • Infection
  • Low sperm count
  • Low testosterone levels
  • Hormonal difficulties
  • Side effects of certain medication

How to increase semen quantity naturally?

If you receive abnormal semen analysis results that indicate low sperm count, you may want to quickly resolve this issue. There are some home remedies and handy tips you can use to boost your sperm count.

Here’s how to increase semen quantity naturally:

  • Exercise regularly – Doing some form of physical activity each day for about 30-40 minutes can help boost testosterone production and lead to an increase in sperm count.
  • Avoid or quit smoking – Smoking cigarettes negatively impacts your fertility by reducing the sperm count.
  • Drink in moderation – Alcohol consumption also hinders your fertility by affecting your sperm health. Avoid heavy drinking or drink in moderation.
  • Consider fenugreek – Fenugreek supplements are known to promote sperm quality and sperm count.
  • Enough Vitamin D – Research suggests that increasing your intake of Vitamin D can also boost sperm health.
  • Add antioxidants to your diet – Antioxidants are popular for their ability to deactivate compounds that contribute to cell damage. Eating antioxidant-rich foods can boost sperm production.
  • Know your fats – You should cut down on unhealthy fats and increase your consumption of healthy fats.
  • Have a nutrient dense diet – Increase your intake of diverse nutrients including folate, zinc, vitamins and minerals.

DNA Fragmentation Index (DFI): Assessing Sperm DNA Integrity

Typically, the chance of infertility being attributed to the male partner are between 35% and 40%. The development of a healthy embryo is initiated when the chromosomes in the egg unite with the chromosomes in the sperm. These chromosomes consist of strands of DNA (deoxyribonucleic acid). The function of the sperm is to deliver male DNA to the egg; the quality of DNA delivered can determine the development of the embryo and subsequent milestones during pregnancy.

Presence of fragmented DNA in the sperm has been shown to affect male fertility potential and development of the embryo.It can also be a cause for IVF failure and recurrent miscarriages. High DFI is generally seen in men with advanced age, inflammation of the external genitals and varicocele, unhealthy lifestyle habits such as smoking and alcohol consumption, and environmental radiation and pollution.

Sperm DNA Fragmentation – Around 50% of most conditions of infertility could be connected to a male element.
Benefits
This procedure helps us understand whether the semen sample from the male partner can be used or not. In case the fragmentation is of a higher degree, we suggest employing a sperm donor.
Risks
The risks that stem from sperm DNA fragmentation have no bearing on the health of the male partner. There are, however, some perceived limitations of the procedure.

Causes of Sperm DNA Damage

  • Drugs, chemotherapy and radiation therapy
  • Cigarette smoking
  • Environmental toxins
  • Genital tract inflammation
  • Testicular hyperthermia (use of hot baths, saunas, laptop computers and prolonged periods of driving)
  • Varicoceles
  • Infrequent ejaculation
  • Advanced age

 

This procedure helps us diagnose the male infertility especially in cases of:

• Unexplained infertility
• Couples with history of poor or arrested embryonic development
• Multiple failed ART cycles
• Recurrent Miscarriage
• Advanced male age
• Varicocele
• Abnormal semen analysis
• Exposure to harmful substances, tobacco, alcohol, radiation etc.

What is sperm DNA fragmentation test?

Since sperm fragmentation deals with the DNA or the genetic material of the sperm, a mere semen analysis is not enough to detect the abnormalities. Specific tests are designed for the same. One of the most commonly used tests is SCSA. SCSA stands Sperm Chromatin Structure Analysis. In this test, the sperm is made to come in contact with a certain chemical dye. If the sperm is broken, its DNA turns red. Similarly, if the sperm is healthy or normal, its DNA turns green. Then, the ratio of the red to green sperm cells is calculated with the help of a specially built software & computer.

  • If the DFI is less than or equal to 15%, the results lie between excellent to good.
  • If the DFI is greater than 15% to less than 25%, the results lie between good to fair.
  • If the DFI is greater than or equal to 25% to less than 50%, the results lie between fair to poor.
  • If the DFI is greater than or equal to 50%, the results are very poor.
